IF statement AIX (Korn Shell Script)

Question

I've made a script which collects info. One of the things it does is checking if a file or directory exists. If yes, it copies it to the /tmp directory.

The script fails with

0403-057 Syntax error at line 3 : `then' is not matched.

This is the statement that fails:

if [ -d /etc/nginx ];
then
cp -R /etc/nginx/* /tmp/
fi

The script is fine. The error you describe most likely means you have Windows-style line endings. I can reproduce it by adding \r to the end of each line:

$ cat script.sh
if [ -d /etc/nginx ];
then
cp -R /etc/nginx/* /tmp/
fi
$ sed 's/$/\r/' script.sh 
$ ksh script.sh 
script.sh: syntax error at line 5: `if' unmatched

You probably edited the file on a Windows computer and that would have inserted \r\n line endings instead of the normal *nix \n line endings. Just remove them and you should be fine:

sed -i 's/\r//' script.sh  

That might not work on AIX's sed though. If it doesn't, use this instead:

sed 's/\r//' script.sh  > tempFile && mv tempFile script.sh

Or

tr -d '\r' < script.sh > tempFile && mv tempFile script.sh
